BENNY BERNSTEIN, OF NEI/V YORK, N. Y.

SPRING-BOLT.

SPECIFICATION forming part of Letters Patent No. 475,922, dated May 31,1892.

Application led November 20, 1891. Serial No. 412,538. (No model.)

To @ZZ whom t may concern:

Be it known that I, BENNY BnRNsTnIN, a citizen of the United States,residing at New York city, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Spring-Boltsfor Doors, dac.; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements in bolts for doors and othersimilar purposes, such as the ends of packingcases, jewelboxes,cabinets, and the like; and it has for its object to provide a device ofsimple and inexpensive construction which can be readily applied andoperated and which will securely hold the door or lid when closed. Theseobjects are attained by the means illustrated in the accompanyingdrawings, in which like reference-numerals indicate like parts in theseveral figures.

In the accompanying drawings, forming part of this specification, Figure1 represents an elevation of a bolt and keeper upon a door, the samebeing in its unlocked position. Fig. 2 represents a front elevation ofthe bolt and keeper detached, the parts being in their locked position.Fig. 3 is a longitudinal sectional view of the bolt and keeper, the samebeing in their locked position. Fig. 4 is a view in perspective of a boxor cabinet supplied with my locking device, and Fig. 5 is an edge viewof the keeper.

The invention consists in an improved combination and arrangement of theparts of the bolt and keeper, as more fully setforth hereinafter, andspecifically claimed.

Referring to the drawings, the referencenumerai l indicates the barrelin which the bolt-bar 2 is adapted to slide. The said barrel is formedwith lateral fianges pierced or formed with openings for the screws, bywhich it is fastened to its seat upon the article to which it is to beattached. The barrel below is formed with two longitudinal recesses 34t, the partition 5 between the recesses being bored or provided with asuitable opening for the passage of the bolt-bar.

The numeral 6 indicates a spiral spring located in the recess et andsurrounding the boltbar. The said spring bears at one end against thepartition 5and at the other end against a projection or screw 7,fastened in the boltbar, or such spring may be otherwise arranged so asto react the bolt when shot. The boltbar is also provided with a stop orprojection 8, which limits its backward movement. The forward end of thebolt-bar is contracted, as at 17, and provided with a sleeve 9, having aweighted depending arm l0, whichi is held against the shoulder ll on thebolt-bar by means of a Iscrew l2 or otherwise, so as to abut closelyagainst the shoulder, but turn freely on the contracted portion 17,before mentioned. The barrel is slotted longitudinally, and through saidslot projects a stud 13, having a knob at its end by means of which thearm may be moved to shoot the bolt-bar.

The numeral 14 indicates the keeper, which consists of a flat platehaving openings for fasteningscrews. Thesaid keeperisprovided with lugsor open lips l5, which are curved upwardly from the edge of the plate,as shown in Fig. 5, which sets next to the forward edge of thebolt-barrel to the opening 18 between the lips, and this opening betweenthe lips is of such size relative to the weighted arm l0 as to permitthe said arm to pass freely therethrough, but of less width than thediameter of the bolt-bar 2, so that said bar cannot pass out betweensaid lips and permit the parts to be accidentallyV opened. The said lipsare also curved at their rear portion to form a seat 16 for the weightedarm l0 when the boltbar is locked and prevent accidental unlocking.

The operation of my invention will be readily understood in connectionwith the above description. To lock the bolt, it is pushed forward, asusual, by the knob of stud 13, the bolt-bar entering the mouth of thekeeper and the weighted arm l0 riding upon the curved lips 15 thereof,and when said arm has passed said lips it falls, and, being drawnbackward by the spring, when released is held by the curve 16 in thelower lip of the keeper on the side opposite that at which it entered.To unlock the parts, the weighted arm is turned upward until on a linewith the opening between the lips, when the tension of the spring drawsit automatically back.

The mouth of the keeper is somewhat larger IOO than the boltbar, s0 thateven should the door sag slightly the bolt-bar Will enter the mouth ofthe keeper and be directed to its lockingseat, and While the mouth ofthe keeper is made larger relatively than the bolt-bar the opening at`the rear of such keeper is only slightly larger than the bolt-bar, sothat a snug lit is assured.

. Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. The combination, in a fastening for doors, box-lids, &c., of abolt-barrel, the boltbar adapted to move longitudinally in said barrel,the spiral spring holding the bolt normally backward, the Weighted armswinging on the outer end of the bolt, and the keeper having open'curved lips, the Whole adapted to be operated substantially in themanner and for the purposes specified.

2. The combination, in a fastening for doors, box-lids, dac., With thekeeper having curved open lips, of a spring-reacted bolt carrying at itsend a swinging Weighted arm adapted to automatically ride upon the lipsof the keeper and fall behind the same when effecting a fastening.

In testimony whereof I affix my signature in presence of two Witnesses.
